Expert Hi,
The advantage of cng is that its cost effective on fuel consumption and reduced emissions.It will be suitable for the engines suitably designed for multiple fuels.With usage of petrol or diesel cars the maintenance costs bound to increase after usage of six months or so.The problem could arise in starting, pickup etc.
